Electric lock valve

Electric lock valveIt is not difficult to see from the literal meaning that this equipment requires higher sealing than ordinary discharge valves and lower air leakage rate. Today, we will further analyze the difference between electric lock valves and ordinary discharge valves from their internal structure, working principle, and how to ensure sealing effect. The sealing of electric lock valves mainly relies on the driving device to drive 8 or more impellers to rotate. Since it is rotation, there must be a pure gap between the shell and the blades. If there is a gap, air leakage will occur, causing poor sealing. How to reduce the air leakage rate and ensure tight air? ButElectric lock valveThe sealing of the impeller relies on a rotating seal, with a gap of only 0.3 millimeters or less between the impeller and the housing. When the impeller rotates to discharge, it offsets the air leakage rate, and the gap between the impeller and the housing is filled and sealed with material. Pressure balance pipelines are added on both sides of the impeller end cover to avoid air flow loops at the discharge port. Two air seals are installed on both sides of the end cover, and copper sleeves are used to replace the external bearings at both ends, which not only avoids air and material leakage on both sides, but also reduces maintenance.
Electric lock valveworking principle
The electric lock valve is installed under the silo or ash silo with positive or negative pressure. The powder enters the volume between the impeller of the electric lock valve through the feeding port by its own weight or pressure, and falls into the pneumatic conveying pipeline or other conveying equipment below with the uniform rotation of the impeller. The feeding amount can be controlled by adjusting the speed and volume of the impeller to achieve timed, quantitative, air locked, and air locked feeding.
